Abstract
Improved Power Density through Use of Powder-Forged Helical Gears in Transmissions.
With the continuing mileage improvement requirements, increasing power density is an important economic consideration in new vehicle design.
This paper describes the power density improvement available through reduced grain size and inclusion levels that are typically found in wrought materials.
The powder forged process is similar to tool steel manufacturing rather than wrought steel manufacturing in that powder is used to manufacture the gear resulting in smaller inclusions than typically found in wrought steel.
